OIL-BURNING FORGE.

Specification of Letters Patent.

Patented Nov. i i i913.

Application filed November 5, 1912. Serial No. 729,596.

To aU fui/ioni if may concern Be it known that I, .loi-in1 Geenen Lernen, a citizen of the United States, residing at Denver, in the couiit-y of Denver and Stat-e of Colorado, have invented a certain new and useful Improvementin Oil-Burning' Forges, of which the following is a specilication.

This invention relates to oil burning forges fory heating drill steels or similar articles and more .particularly to the coiistriiction of the combustion chamber oi such forges.

The' object of the presentV invention is to providea forge in which the combustion olf the fuel will be completely carried out and the flame from the blower `ivill be applied to the articles to be heated in the most eliective and economical manner. With this object in view I have devised a. forge the practical embodiment of which is shown in the accompanying drawings in which:

Figure lis aside elevation part-ly tion, of the whole forge, Fig. 2 is an end elevation partly lin section, on the line 2-2 of lilig. 1 and Fig. 3 is a partial plan view of the forge with the cover removed..

The forge as shown comprises a column l upon the upper end of which are secured the two halves 2,3, of the outer shell ot' the coinbustion chamber ltot the forge these halves of the shellbeing secured together by bolts 5. Insideof this shell is secured the lining of the combustion chamber which consists of two sections G, 7, of refractory material such as lire brick. rl'hese sections together form a chamber the ends of which are seniicylin` drical in shape and from the elongated sides ofwhich project opposite ridges 8, 9', with concave faces Whose radii and centers of curvature approximate those of the seniioylindrical ends, the Whole ,giving a space practically consisting of tivo intersecting cylinders. The upper ends of the ridges 8, 9 are inclined outwardly so that at the top ed the combustion chamber its vsides are straight. Over the combustion chamber proper is placed a cover consisting of an `outer inetal casing 10 with a concave interior surface, in the opposite sides of which are registering apertures l1, l2' extending nearly to the top of the casing. Concave lining blocks 13. 1liare placed .in the ends'oi the cover and are held in place by a rectangular key block 1.3 of

in secs'- ber a cylindrical bore 18 is provided in the front of the combustion chamber which passes through the lining of the chamber and the outer shell. rlhis bore is cut directly through thc ridge 8 in the combustion chainbcr and the center of its opening is in alineinent iviih the. edge of the opposite ridge 9. An oil burner 19 of ordinary construction,

the details oi which foi-iii no part of' the present invention, secured outside ot' theI chamber, its nozzle :20 being alined to direct the flame through the bore 18 directly on to the edgeof the opposite ridge t). The oil burner is provided with fuel and air through fuel pipe 2l and air pipe controlled by the usual valves, 23 'and 24.

rectangular rest bar 25 is secured in. brackets 26, 27 on the front of the lii'ge the upper edge of the bar '253 being sli .litly above the edge of the coiiihustion chain er casing. i

.outer rest bar 28 parallel to and longerthan To support the drill steels or other. articles to be heated a rest bar 25 is provided vwhich is securediiiv place'by arms 29 and 30 which slide in been ing sleeves 3l, 32 on the ends of the combustion chamber casing and which can be held in any desired position by set screws 53. y

To prevent the iianie from coming out ot' the 'frontalieriure of the forge and burning the operator a llame blower is provided which consists of a transverse pipe 34 parallel to and below the rest bar 25 which is provided with a series of air jet holes 35 directed toward the opening of the coiiibustion chamber. This pipe is connected to t-h air supply pipe 22 by a' pipe 3G and the liow of air controlled by. avalve 37. A4 screen 38 is" also held in perpendicular alincmeiit with the rest bar byariiis 39 adjustably secured in the cover casing. l0. f

The operation ol the forge will `be evident lroiii the showing and description; 'lhe particular ad'vaiituireot' the present invention however is derived -.from the shape of the combustion chamber. The Haine entering through the aperture in the ridge 8 passes across the combustion chamber and strikes the. edge of the ridge 9; The nozzle of the burner is so alined that the flame is evenly divided and follows the walls of the eomhustioii chamber around in hothdirections. It is thus given a circular motion and travels in a double ascending spiral to the top of the chamber where it encounters the articlesto he heated. Way the flame is thoroughly distributed throughout the whole combustion ehamher and the flame has sufficient time and length of travel before it reaches the articles to be heated to allow complete combustion of the fuel, thus adding greatly to the etlieieney of the forge.

Although the present furnace is designed for burning oil, itis evident. that. the invention could be adapted for use with any sort of fuel which can he projected through a directing nozzle whether liquid or solid and it is to be understood that the present shoning and description discloses only one specitied modification of my invention and other forms andi-modifications are included in the In this spirit and scope of the invention as lexpressed in the claims.

What l claim is:

1. ln an oil burning forge, an elongated combustion chamber having rounded ends, a vertical ridge on one of the side n'alls of the chamber, a second vertical ridge on the oppositie side wall, having an aperture therethrough, and a fuel burner adapted to direct its flame through said aperture against the opposite ridge.

2. In an oil burning forge, a eoml'iustion ehamher having its interior in the shape of' a pair of intersecting` cylinders with projecting ridges on opposite sides of the chamher. an aperture through one of said pro-` jecting ridges, and a burner arranged to direct its flame through said aperture on to the edge of the opposite ridge said ridge serving to divide the flame.

In testimony whereof, I have hereunto set. iny hand.
